DOUBLE BELT PRESS The SICAM double belt press allows to reach various results: increasing of the density of the product, surface finishing of the product, lamination with permeable or not permeable

The material, between 2 conveyors, passes under pressure between hot and cold plates.

26 DOUBLE BELT PRESS The SICAM double belt press allows to reach various results: increasing of the density of the product, surface finishing of the product, lamination with permeable or not permeable materials on 1 or 2 surfaces with adhesive or by melting fibers. The working principle is based on a combination of heat and pressure. The material, between 2 conveyors, passes under pressure between hot and cold plates. Additional nip rolls between hot and cold zones, properly adjustable, allows to obtain different density on the final product. Double conveyor press after thermobonding oven.
